The present invention is about Cobalt Mountain + W Door A "1. Shoe times or heel strengthening fixing agent, especially about heel strengthening fixing agent. As used herein," Note ,, π, feet are usually worn with 1¾ series, which means Things outside the feet, whether: ready to wear or during manufacturing. … -Shoes, such as sports shoes, require a lighter weight heel strengthening anchor (usually referred to as "heel". ^ Tian, Yi) The light and heavy I heels are made by well-known heel artists. &Quot; & For example, by broadcasting a harder thermoplastic film, laminating on textiles: side or both sides and coating the adhesive, but these are more complicated to manufacture. It is difficult to provide sufficient strength and hardness. The mouth is used to remove individual adhesive layers using thermoplastic materials, which is sufficient for hardness, but it is viscous at the shoe manufacturing temperature and combines with a large number of fibers, so the hardened material is used as a hot-melt adhesive to Combining with shoes. This one is described in Li Gong Li No. 3159, which describes a shoe strengthening anchor, in which a hot-melt adhesive is combined with melted textile fibers and a large amount of f · 隹 々 & Provide a fiber-reinforced hot-melt adhesive shoe to strengthen and fix J film ...: However, this material requires hot-melt adhesive and fiber-reinforcing material to melt the textile to achieve a satisfactory blend of a large number of fibers and adhesives. Various purposes of the invention-'Provide_ Improved toe or heel reinforcement anchoring agent. The present invention can be considered to provide a foot shoe consisting of a mesh structure, or a heel reinforcement anchoring agent, wherein at least some strands are activated at a temperature of 50. A hot-melt adhesive material between C and 80 C.

Date of delivery ^ month (2) ~ ^^ a ~-or' Two types of shoe strengthening anchors according to the present invention may include Different strands-some strands include adhesive polymers, other strands are several "more polymers" whose activation temperature is not viscous between osmium and osmium. For example, the mesh structure can be a kind of Rectangular mesh structure, where the parallel strands extending in one direction are hot melt adhesive strands, and at a right angle there < the strands do not have an activation temperature below 80 ° t (although they can be thermoplastics' But it has a significantly higher temperature). Conveniently,-this kind of-reticular structure and the reinforced anchoring agent according to the present invention is structured and arranged so that when combined with shoes, the hot melt adhesive strands are usually parallel At the heel ', the other right-angled strands are usually at right angles to the heel. However, if desired, the reinforced anchoring agent can be made with other-oriented strands. Weeks are used to make the reinforcement according to the invention The mesh structure of the fixing agent can be manufactured by extrusion method, The melted material is extruded through the holes in the extrusion die to provide multiple strands at regular intervals. Please be familiar with this method and the method is designed so that the strands contact each other while they are still melting This produces a reticulated tissue. This general form of reticulated tissue is commercially available, for example, from Conway, MN 55414, Minneapolis, SE 2810, Weeks Avenue Conwed Plastics. In another reinforced fixing agent according to the present invention, at least some of the strands may be two-component, and one component is a hot-melt adhesive material having an activation temperature between 50 t and 80 t. The activation temperature of the other component is higher than 80. The other component can be selected to give the reinforcing anchor the desired properties, and may be harder or somewhat less hard and more elastic, so that if deformed, the The paper size of the reinforced fixing agent is applicable to the Chinese National Standard (CNS) A4 specification (210X297 public holiday) (please read the precautions on the back before filling out this page).

For example, femur, flat, round, Η-section, multiple round, and 4 睪, by asking the thickness Raise the hardness, or choose to reduce the print through: the risk is that the yarn appears to pass through the material on the leather of the boot, which is unacceptable. According to the invention, the size of the yarn in the shoe strengthening fixing agent is based on Xi Wang {This choice is the same as the size of the opening of the reticulated tissue. The preferred area of the opening of the reticulated tissue in the mouth of Shehua according to the present invention is between 0,03 square centimeters and 0.4 square centimeters. It is more preferably between 0.06 cm 2 and 0.2 cm 2. According to the present invention, the preferred weight of the reinforcing fixing agent is between 250 and 600 grams per square meter (gSm), more preferably between 300 and 450 gsm.

Vinyl carbamate-based adhesive. Suitable polyester base materials can be obtained from Bostik Umited, Leicester, UK, and sold under the names Esterpow or Estergran. In the following, the present invention will be specifically described by using a shoe heel as an example to illustrate the present invention. It will be understood that this shoe heel has been selected to illustrate the invention using examples. B shows a brief military description. In FIG. 1, it is a plan view followed by the explanation. —A brief description of the main symbols in the figure illustrates the meaning of the symbols 8 heels 10 parallel strands 12 strands are explained with the heel 8 is a polycaprolactone mesh tissue cut from Conway Plastics, used to insert shoes In the heel recess in the upper back of the boot leather. Those skilled in the art are familiar with providing a heel recess into which the heel is inserted and held firmly during shoe manufacturing. After cutting, the mesh foot of the heel foot is usually circular in cross section and has a diameter of 1 mm. The skin line is configured to provide a mesh structure with a generally rectangular structure, and a set of parallel strands 10 are arranged, so when the heel 8 is incorporated in the shoe, it usually extends parallel to the heel; another set of strands 12 It will therefore generally extend at right angles to the heel gimbal. The strands are spaced 12 apart so that there are 27 strands in a length of 10 cm, the strands are spaced a little farther apart, and the "strands" are arranged in a length of 10 cm with an interval of about 0.5 cm.

Description of the invention (#) It is stated that the opening area of the heel 8 is about 0.11 cm 2. The weight of the heel is about 340 gsm. After the heel 8 is engaged in the heel recess, heat and pressure sufficient to activate the polycaprolactone to a viscous state, and heat the component to a temperature of about 70 ° C to activate the polycaprolactone adhesive material . After cooling down, the heel 8 provides high rigidity per unit weight and has the added advantage of being breathable. -7s-This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) 498101 A7 _______ B7 Five 'Description of the Invention (5) Compared to a film heel of approximately the same weight per unit area, along the length direction (That is, the direction in which the plate line 12 extends) is relatively large, and the hardness in the transverse direction (that is, the direction in which the strand 12 extends) is approximately the same. From the opening of the reticular tissue, it shows that the heel is breathable. Compared with the film heel, there is a continuous impermeable film to prevent the moisture vapor from passing through. Therefore, wearing instructions are more comfortable with the heel. Xian believes that the size of the strands is so helpful to improve the rigidity of the heel per unit weight, because the strands tend to produce a " bundling, " effect that does not exist in the film heel. Table 1 shows the performance of heel 8 compared to hardened materials of the same weight per unit area known in the prior art. The previously hardened material used for comparison is generally used as a toe hardened material for the toe, and is sold by the patent application company under the registered trademark Tufnex, symbol E268. The two materials usually have a weight per square meter (the same name is called. It means that the size of the heel 8 is larger, and its salt is believed to help improve the hardness. In Table 1, the hardness AL is measured along the length direction. Hardness, that is, the direction parallel to the direction of the strands 12. The hardness Αχ is in the transverse direction, that is, in the direction parallel to the strands. Table 1 (Please read the precautions on the back before filling this page};
